Can you take Collagen and Multivitamin together?

Yes — Collagen isn't a standard multivitamin ingredient, so there's no double-dipping concern; no interaction between the two is established.

A multivitamin covers baseline micronutrients, while Collagen is typically added for skin elasticity, joints, hair & nails (marketed) These roles don't overlap, and no meaningful interaction between them is documented.

For context: a typical daily amount of Collagen is 2.5–15 g, and Collagen has no formal upper limit (generally safe). A typical daily amount of Multivitamin is 1/day, and Multivitamin has no formal upper limit (varies by nutrient).
